Background technique

Air ducts are widely used in buildings for ventilation or exhaust gas removal. For example, after the air pollutants produced by semiconductor processing are collected by the gas collection system, they need to be properly treated so that the pollutants in the air will not harm nature before they can be discharged through the air duct. The production equipment of semiconductor manufacturing is operated in a clean room under strict control, mainly including oxidation furnace, diffusion furnace, cleaning tank, developer, ion implanter and chemical vapor deposition (CVD).
